PROBLEM TO BE SOLVED: To obtain a fiber imparted with functions such as antibacterial, antifungal, deodorizing properties, etc., which are inherent to metal fine particles by depositing specific metal fine particles in a porous fiber having polar groups capable of ion exchanging or ion coordinating, and cross-linking structures. SOLUTION: This metal fine particle-containing fiber is obtained by forming a fiber of porous body from an acrylonitrile polymer having a hydrazine cross- linked structure, polar groups capable of ion exchanging or ion coordinating by converting >=0.1% of the residual nitrile groups into carboxyl groups and forming pores having <=0.85μm pore size, mutually connected and opened on the fiber surface, and ion exchanging or coordinating at least >= one metal ion selected from a group consisting of Ti, V, Cr, Fe, Mn, Co, Cu, Zn, Ag, Cd, etc., e.g. Ag ion, then depositing the metal fine particles by a reducing reaction. |
